The issue is one of visual impact. If it cannot be seen from a road or does not disturb a neigbour's outlook then it wouldn't be difficult. If a neighbour objected, you would have problems.
'Need' is another issue. Having a large dish is not required for standard TV reception, so you would have to argue that you need it to pursue a hobby. That might or might not be considered a good enough reason. A council has to give a good reason to deny permission. It can be challenged.
The law is only a 'by-law'. If you went ahead a put up a large dish, it can only be pursued by the local council if it wants to - or if a complaint is made. The worst that can happen is that a 28 day order is given for its removal.
As
analoguesat suggests, it is only an issue if someone wants it to be. No arrests or fines
Councils do have other powers even over legally sized dishes. If they think it would be better in a different position, they can make you move it.
It is all designed to keep the country looking 'nice'
